Top 10 best castles in Ireland everyone needs to see

Found on river banks, rocky coastlines, or wooded parks, here are ten of the best castles in Ireland that everyone needs to see.

Ireland’s long and tumultuous history is intertwined with both Irish kings and British royal intervention, and one of the remaining leftovers of this are many stunning, historic castles that are scattered throughout the Emerald Isle. 

Ireland is now a republic, and thus castles no longer have any official connection to the state or power. With over 30,000 castles and their ruins to be found throughout the country, here are ten Irish castles we think everyone needs to see.

10. Blarney Castle (Co. Cork) – kiss the stone

Blarney Castle is famous for the ‘Blarney Stone’, located at the top of the castle. It is believed that kissing the stone bestows upon the culprit the ‘gift of the gab’.

This once medieval fortress was built over six hundred years ago by former Irish chieftain Cormac MacCarthy, and is now “one of Ireland’s greatest treasures”, according to the castle’s website.

Address: Monacnapa, Blarney, Co. Cork, Ireland
